F-Secure Internet Security 2015 offers a reconfigured installation process, safer search filtering, and a prescan utility to help with those tough cleanup jobs. Also new is the F-Secure Safe bundle, which aims to secure all your devices (PC, Mac, Android, iOS, and Windows Phone 8), including measures for managing a missing phone.

Pros

Quick and effective setup: Installing Internet Security 2015 is a breeze. F-Secure prompts you with a one-click process. You can also install browser plug-ins for Browser Protection and F-Secure Search, a search result filter. With the 2015 edition, F-Secure introduces a prescan cleanup tool that searches for and removes malware upon the initial installation, easing cleanup on compromised systems.

No more launchpad: You no longer have to dig around to open a menu, as the main application now presents a clear and straightforward UI.

Parental settings let you set a usage limit: With the Browsing Protection plug-in, you can manage and limit the search results of popular search engines for individual Windows users.

Lightweight protection: F-Secure scored 99 percent in real-world protection tests from independent lab AV-Comparatives, so F-Secure maintains its reputation as a consistently reliable Internet security suite that takes very little toll on system performance. We had no trouble running a quick scan while performing everyday tasks. But if you don't want to be interrupted by scans while playing games or watching movies, Internet Security has a game mode.

Cons

Bland UI: By dropping the launchpad, F-Secure fell back to the traditional text menu and basic buttons for initiating tasks. Its utilitarian design is functional but bland.

Quirky browser protection: Although the suite is capable of censoring Web content, Browser Protection behaved unpredictably during our tests. The app warned of a supposedly blocked site, but we were able to get access. Protections were designed for popular browsers like Internet Explorer, Firefox, and Chrome. More tech-savvy kids may attempt to circumvent Browser Protection through other third-party browsers, but won't be able to bypass the manually set Internet blocking feature.Bottom Line

Internet Security 2015's straightforward UI and high security performance score show that F-Secure's mission is usability and efficiency. Additional features like Safe Search and Parental Controls are nice touches, and prescan utilities are helpful for infected PCs. Ultimately, F-Secure Internet Security is a no-nonsense security suite that just works.
